Is it true that the bigger spincer the scorpion has will be the lesser it's dangerous

i've heard that if a scorpion has a big spincer, it's venom will be less dangerous. I am just thinking of something flashy to do.

basically yes although your grammar makes the question difficult to read.

a large scorpion with big nasty pinchers doesn't need a strong venom to subdue its prey, it simply holds it and starts munching. and small scorpion with dainty pinchers can't hold struggling prey so easily so it needs a strong venom to knock it out so that the scorpion can dine without difficulty.

Yes it's very true and the mistake of the smaller the less harmful causes many fatalities and serious injures. The scorpion either relies on it's venom or pincers not both. So if it has massive scary pincers then its sorted. You Wont go near it and if you do you will get what you should have expected, a mighty nip. But if the scorpion has small pincers then it's scuppered, but luckily it has the next best thing, super powerful venom, much tougher than pincers. You or it's prey will be dead within a very short period of time.it's reflexes are those of a king cobras so a surprise attack is certain and so is injury of fatality.

With one major exception, yes, it's the small ones you need to watch out for. The exception is the Iranian Deathstalker, but I assume you're not planning on going into the Middle East anytime soon.

For something that's pretty much harmless, look into getting an Asian or Emperor Scorpion.
